Over the past 24 hours solar activity has returned to B-class eruptive level. There have been seven B-flares flares originated at NOAA AR 2645 (McIntosh:Dai; Mag.Type:Betta-Gamma).The biggest flare B4.5 peaked today (29-Mar-2017) at 01.40 UT originated at NOAA AR 2646 (McIntosh:Axx; Mag.Type:Alpha) which is about to rotate over the east limb. No Earth- directed CMEs have been detected over the past 24 hours. Solar protons have remained at background levels over the past 24 hours. Solar X-Ray background level is expected to remain low. NOAA AR 2645 is expected to produce more B-class flares over the next 24 hours. C-class flares are also not excluded. Over the past 24 hours, solar wind speed measured by DSCOVR remained stable with the average value around 700 km/s till 06:00 UT today (29-Mar-2017). Then the speed dropped abruptly till 630 km/s. WSA-ENLIL model indicates the Earth is out of influence of the high speed stream. Interplanetary Magnetic Field (IMF) remained stable with the value around 4 nT. Bz variations remained at low level (varying mostly between -4 nT and +4nT). The geomagnetic field stayed at active conditions level (K Dourbes between 2 and 4; NOAA Kp between 3 and 4). Active to unsettled geomagnetic conditions (K Dourbes < = 4) are expected today and tomorrow.
Today's estimated international sunspot number (ISN): 047, based on 16 stations.
